直接将下边的类拖入项目即可（重写NSDictionary和NSArray的方法）
#import <Foundation/Foundation.h>

[string appendString:@"{\n"];
// 遍历所有的键值对

[string appendString:@" : "];
[string appendFormat:@"%@,\n", obj];
}];
// 结尾有个}
[string appendString:@"}"];
// 查找最后一个逗号
NSRange range = [string rangeOfString:@"," options:NSBackwardsSearch];
if (range.location != NSNotFound)
[string deleteCharactersInRange:range];
return string;
}
@end
